Great, reliable, drought-resistant once established, virtually care-free. I've never had a penstemon I didn't like, and this one is no exception.

Mine's planted in moderately-rich soil where it gets sunshine nearly all day, fed in early spring with Plant-tone and a bit of compost - this is the time to press them back into the soil if they've been heaved up from the ground during winter freezing/thawing cycles.

I'll give them a deep soaking if we've had a prolonged dry spell, but otherwise I neglect them, and they do just fine.

Very reliable. Delicate yellowy-green foliage. Begins blooming in May, slows in summer. With cooler temps in autumn it is again covered in fresh leaves and flowers.

The color is a grape-purple. The flowers are "tubular" like all penstemon, but short and robust like a foxglove.

It's planted in rich soil in full sun with normal waterings and never needed any special care. It doesn't seem to mind heat with humidity, unlike other penstemon I've tried (and failed) to grow.

UPDATE: Somehow I became disenchanted with the color of this plant and I pulled it out. The following year it was back as nice as before, from some roots that remained. I'm glad I failed to remove it, because it's so reliable and looks great with some new neighbors I added in the meantime. This plant also seeds readily and grows easily from cuttings. I am developing this into a larger clump from cutting and volunteers, but also simply by stretching out a stem and burying it while it's still attached to the parent plant; the stem will root in a suckering fashion. Hummingbirds and bees are attracted to this plant.

Plant in a full sun location with well drained soil. It can tolerate drought conditions. Great for zones 5 - 8. Small purple flowers bloom all summer long. The plant, with flowers, can reach a height of 15". Attracts hummingbirds and butterflies, too. A fast grower.
